Enhanced visibility and exposes vulnerabilities but needs more integration
I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…
Corrado Vigano - PeerSpot reviewer
Solution integrates well with existing systems while being easy to use
The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use. Furthermore, Microsoft's reliability in providing a clear roadmap for the solution is very important, especially at a time when cybersecurity is a risk in every company. The solution is easy to reuse and not difficult to find expertise for in the market because it is widespread. It is gaining attention even from partners and from the market on the offering side. This serves as a good starting point for customers who can develop internal competence on the solution. Additionally, the presence of reliable partners who know the solution and can provide internal knowledge is the best aspect for them.

Cons

"With Microsoft, support is always crazy, it's not easy to get support."
"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"The quality of Microsoft customer support varies. With an enterprise contract, good resources are usually provided, especially in regions like Saudi Arabia or UAE. However, we have faced challenges with support quality, especially in some subcontinent areas where the resources might not be as experienced."
"A common concern among the customers I visit is the unpredictability of Microsoft's costs at every renewal. This is really bothersome for the customer, and I would say it is the worst element I have seen in these years."
"I would like to see faster synchronization."
"The support engineers are not as skilled as our engineers. When they say something would not work, or there is no solution, we usually hear that Microsoft would not support this."
"The cost is very high."
"The problem with Microsoft products is that they often cater to enterprise-level needs, which can be too costly for medium-sized businesses."
"Microsoft's pricing is complex and difficult to fathom due to a range of different licensing options."
"There have been a couple of times when it was unavailable because of Microsoft issues, but other than that, I don't remember any problems."
